When you launch node A you will be given an address for connections.
So on node B, use that address:
multichaind chain1@1.2.3.4:7217
You will then see a message like this:
Please ask network admin to let you connect and/or transact:
multichain-cli chain1 grant 1FYGNwDvThGvPC8kEoaDsuWV5TNdKebXgAZ1J5 connect
multichain-cli chain1 grant 1FYGNwDvThGvPC8kEoaDsuWV5TNdKebXgAZ1J5 connect,send,receive
So on node A, grant the permission so node B can connect:
multichain-cli chain1 grant 1FYGNwDvThGvPC8kEoaDsuWV5TNdKebXgAZ1J5 connect,send,receive
Back on node B, you can now launch multichain:
multichaind chain1@1.2.3.4:7217 -daemon
On Node A, let's make an asset and transfer it to node B:
multichain-cli chain1 issue 1A2wdhVs4KduhKMxEKKxrGNwEnsdhayJaVawMY euro 1000
Then you can send using the name of the asset:
multichain-cli chain1 sendassettoaddress 1FYGNwDvThGvPC8kEoaDsuWV5TNdKebXgAZ1J5 euro 100
